Mortgages at the speed of trust.

+

Distributed lending, community-funded tranches.

+

+ A 30-year mortgage split into 80 tranches of $5k, each funded by a neighbor, backed by + social trust instead of a credit score. Reinvestment loops turn idle capital into yield. + A secondary market lets lenders exit when they need to. +

What rLending Handles

+
+
+
🤝
+

Trust-Backed Lending

+

Underwriting from your community, not a bureau. Trust scores from rNetwork relationships and rCred reputation replace FICO.

+
+
+
🧺
+

Distributed Tranches

+

One mortgage, many lenders. Each lender picks a term (2yr–30yr) and rate, funding a $1k–$5k slice of principal.

+
+
+
📈
+

Reinvestment Loops

+

Repayments auto-roll into new tranches or external DeFi yield (Aave v3, Morpho Blue). Compounds while borrowers pay down principal.

+
+
+
🔅
+

Secondary Market

+

Lenders can list their tranche for sale at any time. Buyers step in, premium is set by supply and demand.

+
+
+
+
+ + +
+
+

How It Works

+
+
+ 1 +

Borrower Posts Terms

+

Property value, down payment, term, rate. The simulator splits the principal into configurable tranches and tiers.

+
+
+ 2 +

Community Funds the Tranches

+

Lenders in the space claim tranches that match their risk tolerance and time horizon. Trust from your network gates access.

+
+
+ 3 +

Payments Flow & Compound

+

Monthly payments amortize each tranche. Reinvestment rules auto-deploy idle capital to new tranches or Aave/Morpho.

+
+
+
+
+ + +
+
+
+
+

Pool economics, not banks

+

+ Every dollar stays in the community. Interest that would have left as bank profit now recycles as yield for neighbors. +

+
    +
  • Variable terms — 2yr, 5yr, 10yr, 15yr, 30yr tiers with tiered rates
    • +
  • Overpayment — extra principal, community fund contributions, or split
    • +
  • Pool reinvestment — idle capital earns Aave v3 supply APY until redeployed
    • +
  • Simulation modes — mycelial, flow, grid, lender, borrower views
    • +
+
+
+
+
📈
+

Aave v3 + Morpho Blue

+

Live pool reinvestment.
APY updates on every block.

+
+
+
+
+
+ + +
+
+

Built on Open Source

+

The libraries and tools that power rLending.

+
+
+
⚖
+

ERC-20 & Aave

+

Open stablecoin rails. Supply to Aave v3 for idle pool capital, borrow against positions for leverage.

+
+
+
🌠
+

rNetwork Trust Graph

+

Underwriting draws on your community's trust edges, not an opaque credit score.

+
+
+
📡
+

Automerge CRDT

+

Positions and tranches sync live across lenders. No central ledger, no single point of failure.

+
+
+
🔥
+

Hono

+

Ultrafast API layer. Lightweight and edge-ready.

+
+
+
+
+ + +
+
+

Model a mortgage your whole block can fund.

+

Run the simulator and see how your community can replace the bank.
